Pruning of Lantana camara L.
Regular pruning helps Lantana camara L. to maintain a compact growth habit, promotes branching, and enhances flowering. Prune the plant after flowering, cutting back the stems to about half their height. It is also essential to remove dried or diseased leaves, stems and flowers regularly. Pinching out the new shoots during the growing season helps shape the plant and promote bushy growth.
Propagation of Lantana camara L.
Lantana camara L. can be propagated through various methods, including:
Seed Propagation
The most common method of propagating Lantana camara L. is through seeds. Seeds are collected from the mature fruits and sown in trays or small pots containing seed-raising mix. The seeds should be sown at a depth of around 2-3 mm and kept moist until they germinate.
Once germinated, Lantana camara L. seedlings should be gradually acclimatized to outdoor conditions and then transplanted into their final growing position.
Cutting Propagation
Another propagation method for Lantana camara L. is through stem cuttings. Cuttings around 8-10 cm in length can be taken from the parent plant during the active growing season. The cuttings should preferably be taken from semi-hardwood or hardwood growth, as this will increase the chances of rooting.
Remove the leaves from the lower half of the cutting and then dip the cut end into rooting hormone powder. Insert the cuttings into a well-draining propagation mix and water them regularly. Once rooted, the cuttings should be transplanted into small pots and then gradually acclimatized to the outdoor conditions.
Division Propagation
Division propagation is suitable for mature Lantana plants that have developed a strong root system. It involves carefully dividing the parent plant into smaller clumps, ensuring that each clump has a healthy root system. The clumps are then transplanted into their final growing position and watered regularly until established.
Propagation of Lantana camara L. is relatively easy, and any of the above methods can be used. However, it is essential to ensure that the new plants are regularly watered and fertilized until they are established.
